Is Solar Still Worth It in California in 2026? The Honest Answer for PG&E, SMUD, SCE & SDG&E
Short answer: Yes — but the strategy has changed. NEM 3.0 didn't kill solar in California. It changed the game from grid export to self-consumption. Here's the honest 2026 breakdown for PG&E, SMUD, SCE, and SDG&E homeowners.
If you've been sitting on the fence about solar — or you've heard that NEM 3.0 "killed" the economics — this post gives you straight answers based on actual 2026 rate data across all four major California utilities. No sales spin. No outdated numbers.
What Did NEM 3.0 Actually Change for California Solar Customers?
NEM 3.0 reduced export credits — the money solar customers earn for sending power back to the grid — by roughly 75% compared to NEM 2.0. That is the single most important change to understand before evaluating whether solar makes sense in 2026.
NEM 3.0 took effect for new solar customers on PG&E, SCE, and SDG&E in April 2023. Under the previous NEM 2.0 system, excess solar sent to the grid earned near-retail credits — effectively using the grid as a free battery. NEM 3.0 closed that approach by drastically reducing what utilities pay for exported solar.
What NEM 3.0 didn't change: the cost of buying electricity from the grid. PG&E, SCE, and SDG&E rates kept climbing regardless of the policy change. Every kWh of solar you generate and use yourself is still worth exactly what you'd otherwise pay for it at retail rates — and those rates are among the highest in the country.
The strategic shift in plain English: Solar went from an export game to a self-consumption game. The goal now is to use your own solar generation on-site rather than sell it back at low rates. A battery makes this possible — storing daytime solar and discharging it during the expensive 4–9pm peak window every evening.
Is Solar Worth It in 2026? The Answer by California Utility
Whether solar makes financial sense in 2026 depends almost entirely on which utility you're with. Here is the direct answer for each of the four major California utilities.
| Utility | Avg Blended Rate | NEM Status | Battery Needed? | 2026 Verdict |
|---|---|---|---|---|
| PG&E | ~$0.38/kWh | NEM 3.0 | Essential | Strong — solar + battery |
| SDG&E | ~$0.47/kWh | NEM 3.0 | Essential | Strongest case in US |
| SCE | ~$0.35/kWh | NEM 3.0 | Essential | Strong — solar + battery |
| SMUD | ~$0.13/kWh | NEM 2.0 Active | Optional | Good — solar-only works |
PG&E Territory
PG&E serves most of Northern and Central California — Fresno, Sacramento, Stockton, Vacaville, Bakersfield, and surrounding communities. At roughly $0.38/kWh blended, with peak rates hitting $0.45+ per kWh during summer evenings, every kilowatt-hour of solar self-consumed avoids a meaningful grid charge. Under NEM 3.0, battery storage is required to capture that value. A properly sized solar + battery system can cover 85–100% of annual PG&E usage through self-consumption.
SDG&E Territory
SDG&E customers have the strongest financial case for solar of any utility in the United States. At approximately $0.47/kWh blended — the highest residential rate of any major US utility — every kilowatt-hour of self-generated solar carries maximum financial value. Solar + battery systems pay back faster in San Diego than anywhere else in California.
SCE Territory
Southern California Edison serves much of the Los Angeles basin and Inland Empire. SCE's NEM 3.0 dynamics mirror PG&E's — battery storage is essential for new solar to pencil. SCE's TOU-D-PRIME rate plan, which applies to NEM 3.0 solar customers, rewards high self-consumption and makes a well-designed solar + battery system financially strong.
SMUD Territory
SMUD is the outlier — Sacramento's municipal utility still operates under NEM 2.0, offering near-retail export credits for excess solar. Solar-only systems still pencil well without battery storage. Battery adds meaningful additional value: SMUD offers a rebate of up to $5,400 per Powerwall plus a $440/year Virtual Power Plant credit for Tesla Powerwall customers who enroll within 90 days of Permission to Operate. Verify current amounts at smud.org — subject to change.
SMUD homeowners: NEM 2.0 will eventually change. The best time to interconnect under favorable terms is before that happens. Homeowners who act now lock in their export rate structure for the life of the system.
How Does the Prepaid Lease Work If There's No Tax Credit?
The federal residential solar tax credit (ITC/25D) is no longer available to individual homeowners for systems placed in service from 2026 onward. This surprises many homeowners who heard solar came with a 30% tax credit.
The workaround that preserves the savings: the prepaid lease structure. A third-party system owner purchases and installs the system, claims the investment tax credit — which only third-party owners still qualify for through 2027 — and passes 30% savings directly to you as an upfront price reduction. You get the equivalent of the tax credit benefit without needing any tax liability. No filing, no waiting, no income requirement.
After five years, you have the option to purchase the system. After that point you own it outright. This structure is available through 2027 and is how most California homeowners are financing solar + battery today.
What Do the Real Numbers Look Like for a California Homeowner?
Here is a straightforward example for a PG&E homeowner currently paying $400/month in electricity — a common bill level across Central California.
| Scenario | Monthly Cost | Year 10 Cost | Year 25 Cost |
|---|---|---|---|
| No solar — PG&E only (4% annual increase) | $400 | ~$592/mo | ~$1,066/mo |
| Solar + battery — financed $0 down | $225–$350 loan + $25 PG&E | Same loan payment | $0 after payoff |
| Solar + battery — cash purchase | $25 PG&E only | $25/mo | $25/mo |
The $25/month figure is the PG&E Base Services Charge — the fixed monthly connection fee that applies to all customers including solar, as of March 2026. A properly sized solar + battery system eliminates all usage charges, leaving only this fixed fee.

Quick answers to the questions we hear most from California homeowners evaluating solar in 2026.
No. NEM 3.0 changed the strategy, not the outcome. Under NEM 3.0, solar works through self-consumption rather than grid export. A properly designed solar + battery system can eliminate 85–100% of your PG&E, SCE, or SDG&E bill by storing daytime solar and using it during the expensive 4–9pm peak window — avoiding export to the grid entirely. The financial case remains strong, particularly for homeowners paying over $150/month to their utility.
For PG&E, SCE, and SDG&E customers — yes, battery storage is now essential for solar to fully pencil under NEM 3.0. Without a battery, excess daytime solar gets exported to the grid at low NEM 3.0 rates, dramatically reducing the system's financial return. A battery captures that excess generation and discharges it during peak hours when grid electricity costs the most. SMUD customers on NEM 2.0 are the exception — solar-only still works well in Sacramento territory.
The federal residential solar tax credit (ITC/25D) is no longer available to individual homeowners for systems installed in 2026 or later. However, the 30% savings is still accessible through the prepaid lease structure: a third-party system owner purchases the system, claims the investment tax credit — which third-party owners still qualify for through 2027 — and passes the 30% discount to you as an upfront price reduction. No tax liability required. This is the most common financing structure for California solar + battery systems today.
For most California homeowners, a solar + battery system pays back in 8–9 years. This assumes current rate levels and a 4% annual rate escalation — a conservative estimate given that California utilities have averaged 6–8% annual increases over the past decade. After payback, the system continues generating effectively free electricity for the remaining 15+ years of its useful life. SDG&E customers typically see faster payback due to the highest rates in the country. SMUD customers may see slightly longer payback due to lower base rates, partially offset by available battery rebates.
For most California utilities, a monthly electric bill of $150 or more makes solar + battery worth evaluating. At that level, the system savings typically exceed the financed loan payment from day one — meaning you spend less on energy the month the system turns on than you did before. Homeowners paying $200–$400/month or more see the strongest financial case. Homeowners paying under $100/month may find the payback period too long to justify the system cost, though this threshold is lower for SDG&E customers due to their higher rates.
